BudgetClaw

v1.2.0

Local spend monitor for Claude Code. Tracks cost per project and git branch, warns you before a cap, and kills the process when you blow past it.

Per-project, per-branch budget caps (daily / weekly / monthly)
Phone alerts via ntfy -- install the app, subscribe to a topic, run budgetclaw alerts setup
SIGTERM on breach + lockfile that catches silent relaunches
Point-in-time pricing from the open ai-price-index dataset (CC BY 4.0), embedded at build time so it stays fully offline and prices each event at the rate in effect when it ran
Optional budgetclaw sync pushes aggregate spend rollups to a Goei dashboard. Only dollar and token totals leave the machine, never prompts or keys.
Zero keys. Zero prompts. Reads local logs only.
Single Go binary, 5 MB, no runtime, no account

Frequently asked questions

What is RoninForge? +

A small collection of free, open-source developer tools for people shipping solo. Every tool is MIT licensed, runs locally, and works with the AI coding stack (Claude Code, Cursor). No accounts, no dashboards, no cloud lock-in.

Who is this for? +

Independent developers who ship without a team. People leaning hard on AI coding tools and wanting to keep control of cost, data, and process. Terminal-native, skeptical of vendor lock-in, happy to read source.

Why the name RoninForge? +

A ronin was a samurai without a lord. Shorthand here for working independently by choice, without a company behind you. The tools are built for that audience. The forge is where the work gets hammered out.

Is everything really free and open source? +

Yes. Every repo is MIT licensed. No paid tiers, no subscriptions, no waitlists. If a future tool needs hosted infrastructure that costs us money, it gets labeled clearly and stays opt-in. Nothing shipped today requires that.

Do the tools phone home or collect telemetry? +

No telemetry, no crash reports, no usage analytics in any CLI. The only network calls are ones you configure yourself, like your own ntfy topic for phone alerts. The source is auditable in an afternoon.

How does RoninForge make money then? +

Today, it doesn't. RoninForge exists to build a reputation first. Revenue comes later from a separate paid product built on top of this work, labeled clearly as such. The free tools stay free and MIT.

RoninForge builds free, open-source tools for developers who prefer to own their stack. Everything runs locally. Every repo is MIT licensed. No accounts, no tracking, no vendor lock-in.
